Title: Mitsutoshi Kaneyasu: Innovator in Spring Technology
Introduction
Mitsutoshi Kaneyasu is a notable inventor based in Kamiina-gun, Japan. He has made significant contributions to the field of spring technology, holding 2 patents that showcase his innovative designs and engineering expertise.
Latest Patents
Kaneyasu's latest patents include a damper spring device, a flywheel, and a clutch disk for a lockup mechanism. The damper spring device features a first spring and a second spring retained by a stopper, allowing the second spring to be compressed by a preload that is greater than that of the first spring. This design ensures that the first spring deforms under specific axial loads, while both springs deform under greater loads. Additionally, he has developed a coil spring that is highly resistant to permanent set and fatigue. By controlling the thickness of the nitrization layer on the surface, the coil spring can endure 10^7 cycles of repeated high stress without significant permanent set.
